During the April 2020 update, Bosses had Willpower limits placed on them. This became known as a Protection Status. This allows newer players and low Willpower players the chance to kill bosses for rewards.
Please Note that this guide was updated to add the Mastery levels of Willpower. I am still unsure if there will be a Mastery level above 6. So, you may need to watch your Willpower level too.The list below is the Willpower needed to hit a boss and the Max Limit before you need to wait for the Protection Status to be over, which means a Higher Willpower player can kill the boss.
